Condensed Forging stretching from the high-toe area and along the topline of the iron blade enhances overall strength, durability, and feel. Then the forged faces on ZXiU are softened to improve this already exceptional feel.

MainFrame iQ is a variable-thickness network of grooves, channels, and notches precision milled into the back of every ZXi5, ZXi5+, and ZXiU Utility Iron face. At impact, these features flex together to maximize energy transfer for more speed, more consistently, across the face.

Srixon's Tour V.T. Sole takes turf interaction to a whole new level of detail with a proprietary combination of sole widths, bounce angles, and notches. This technology encourages a smooth glide through fairway, rough, and sand without losing speed, even if you enter the turf slightly behind the ball.

Guided by Srixon's tour staff, every new ZXi Iron has been refined for a cleaner, more exacting profile, featuring slightly thinner toplines than the previous generation.

Every new ZXi Iron face and body are forged at Japan's premier forging house: Endo, the gold standard in iron forging. A place that refuses to compromise on feel.

A forged S20C steel body absorbs vibrations for an extremely soft feel, while a high-density tungsten weight in the sole of each ZXi Utility Iron helps keep speed and spin consistent on off-center strikes.
